Therefore, compared to the case where the folding height is H, the loss of structural thickness is reduced, and there is no need to fold in a shape-retaining separator made of synthetic resin or the like together with the filter member. In addition, by eliminating the need for non-breathable separators, there is no loss of filtration area of the filter members 42, 43, and there is no structural pressure loss due to the presence of the separators.

In addition, when arranging the filter members 42 and 43 in multiple stages, for example, filter parts 42 and 43 having different http collection performance may be arranged.

Since the combinations of can be freely selected, it is easy to make the exhaust filter 41 multi-functional and high-performance, and it can easily correspond to various specifications.

In the illustrated embodiment, the filter members 42 and 43 are stacked in two stages, but the filter members may be stacked in three or more stages in the folding direction of the pleats.

In addition, since the filter members 42 and 43 having a multi-stage structure are adhesively fixed to one box-shaped holding frame 44 while maintaining airtightness,
The exhaust filter 41 is easy to handle when it is assembled into the main body 11.

In the above embodiment, the holding frame 44 is made of an integrally molded product, but the holding frame may be molded separately on the left and right sides, and later fixed to the left and right sides with the filter members 42 and 43 in between. good.

By the way, glass fibers have conventionally been used as the wood for the high-density filter member 1. However, the filter member 1 made of glass fiber has a large pressure loss itself, and also has a large loss of III-forming pressure when formed into a pleated structure, which has an adverse effect on suction performance and the like. On the other hand, in the above embodiment, instead of glass fiber, a plurality of X ifi materials 42a, 42b, 4 made of, for example, synthetic fiber, composite fiber, or electrostatically processed material are used.
3a and 43b are laminated by lamination processing or bonding processing to form a multilayer filter member 42.
．． 43, and the filter members 42 and 43 are folded into pleats, making it possible to sufficiently collect fine dust while reducing pressure loss.

In addition, by making any of the P materials 42a, 42b, 43a, 43b in the filter members 42, 43 with a multilayer structure to have deodorizing, deodorizing, antibacterial effects, etc., the same as described above can be achieved. As you can see, the exhaust gas can be cleaner.

Further, by embossing the weak filter member 112.43 in accordance with the pleat bits, folding to form a pleat shape becomes easier.

Furthermore, especially compared to glass fiber, the filter portion 4442
．． Since the specific gravity of the exhaust filter 43 itself is small and the synthetic resin separator is unnecessary as described above, the exhaust filter 41 can be made lightweight.

In addition, in the illustrated embodiment, the filter members 42, 43 are 2W
Although a J structure is used, three or more layers may be used. Further, by forming the filter members 42 and 43 with a multilayer structure as described above, excellent effects can be obtained.
43 may be made of glass, in particular in a layered structure.

(Effects of the Invention) According to the present invention, since the plurality of filter members folded into pleats are stacked in multiple stages in the folding direction h of the pleats,
In manufacturing, by combining a filter member with excellent dust collection performance and a filter member with an 8!1 odor effect, it is possible to make the exhaust air cleaner. Since the exhaust filter can be freely selected, it is easy to make the exhaust filter have a wide variety of functions and high performance. In general, since the plurality of filter members are adhesively fixed to one holding frame, it is not difficult to handle them when assembling them to the main body of the filter.
